Understanding Solo 401(k) or Self-Employed 401(k)

A Solo 401(k) – also known as a Solo K, Uni K, Self-Employed 401(k), Individual 401(k), or One-Participant 401(k) – is a retirement savings plan specifically designed for self-employed individuals or business owners with no full-time employees, barring a spouse who works for the business.

Unlike traditional 401(k) plans which are typically provided by an employer for their employees, Solo 401(k)s offer a unique set of advantages for those who are their own boss. So, if you’re running a sole proprietorship, a partnership, or a limited liability company and don’t employ anyone apart from your spouse, this might be the perfect retirement solution for you.

To provide some context, consider the story of John and Sarah, a couple who run a freelance design agency. They had been contributing to Individual Retirement Accounts (IRAs) but were looking for ways to put away more for their retirement while also reducing their taxable income. After learning about the Solo 401(k), they were able to significantly increase their retirement savings rate and enjoy considerable tax benefits.

Eligibility Criteria for a Solo 401(k)

In the world of retirement planning, understanding eligibility criteria is paramount, especially when it comes to maximizing your savings. So, who exactly is eligible for a Solo 401(k)? Let’s explore:

  1. Self-Employment Income: The primary eligibility criterion for a Solo 401(k) is having self-employment income. This means you’re earning income by freelancing, running your own business, or working as an independent contractor. It doesn’t matter whether your self-employment activity is full-time, part-time, or something you do on the side. As long as you’re generating self-employment income, you’re eligible.
  2. No Full-Time Employees: Another critical aspect of the Solo 401(k) is right in its name: Solo. You can’t have any full-time employees working for you, other than your spouse. The IRS defines full-time employees as those who work 1,000 hours or more per year.
  3. Age and Income: Unlike Roth IRAs, which have income restrictions and traditional IRAs, which have age restrictions, Solo 401(k)s have no such constraints. Regardless of your age or how much you earn, you can contribute to a Solo 401(k) as long as you meet the self-employment and no full-time employees criteria.

Remember our dynamic duo, John and Sarah? As freelancers, they qualified for a Solo 401(k) because they earned self-employment income and had no employees apart from themselves. They were able to take advantage of the high contribution limits and other benefits the plan offers to bolster their retirement savings and prepare for a financially secure future.

Understanding the eligibility criteria is your first step towards harnessing the power of a Solo 401(k). If you’re self-employed and have no full-time employees, you might just have found the retirement savings solution that could transform your financial future.

Benefits of a Solo 401(k)

What sets the Solo 401(k) apart from other retirement plans? Here are the top five benefits:

  1. Higher Contribution Limits: Compared to traditional IRAs or SEPs, a Solo 401(k) allows for higher contribution limits, potentially making it a powerful tool for building your retirement nest egg faster.
  2. Tax Benefits: Contributions to a Solo 401(k) are typically tax-deductible, providing a helpful reduction in your current taxable income. Moreover, your investment earnings can grow tax-free until withdrawal.
  3. Loan Option: Unlike other retirement plans, Solo 401(k)s offer a loan provision. You can borrow up to 50% of your account balance (with a cap at $50,000) without any penalties or taxes.
  4. Flexibility: You can choose between a traditional Solo 401(k) and a Roth Solo 401(k), depending on whether you prefer to get a tax break now or enjoy tax-free withdrawals in retirement.
  5. Creditor Protection: Solo 401(k)s generally offer robust protection against creditors under federal law, adding an extra layer of security to your retirement savings.

Let’s revisit John and Sarah for a moment. By setting up a Solo 401(k), they were able to contribute up to $66,000 in 2023, a significant step up from the $6,000 contribution limit of their previous IRAs. The tax benefits were also quite appealing, as their contributions effectively reduced their taxable income, leading to lower tax bills.

Setting Up a Solo 401(k)

Now that we’ve covered the benefits, let’s delve into the nuts and bolts of setting up a Solo 401(k). Establishing your Solo 401(k) is a relatively straightforward process, but it involves several crucial steps:

  1. Check Eligibility: The first step is to ensure you meet the eligibility requirements. You must have some self-employment income and have no full-time employees other than a spouse.
  2. Choose a Provider: Next, choose a financial institution to establish and administer your Solo 401(k). Research thoroughly and compare various providers based on costs, investment options, customer service, and additional features like loan provisions or Roth options.
  3. Decide on the Type: Determine whether a traditional or Roth Solo 401(k) best suits your needs. Remember, with a traditional Solo 401(k), contributions are made pre-tax, but withdrawals are taxed in retirement. On the other hand, Roth contributions are made after-tax, but withdrawals are tax-free in retirement.
  4. Set Up the Plan: Once you’ve chosen a provider and the type of plan, you’ll need to complete the necessary paperwork. This typically includes a plan adoption agreement and account application.
  5. Make Contributions: Finally, start making contributions to your plan, keeping in mind the annual contribution limits. Remember, you can make contributions as both an employer and an employee.

After successfully setting up their Solo 401(k), John and Sarah found themselves not just with an efficient retirement savings tool, but also a newfound sense of financial confidence. They were now in control of their retirement destiny.

Contributing to a Solo 401(k)

How much can you contribute to your Solo 401(k)? The answer lies in the unique structure of the Solo 401(k), which allows you to wear two hats: that of the employee and the employer. In 2023, as an employee, you can make a deferral contribution of up to $22,500. If you’re 50 or older, you can contribute an additional $7,500 as a catch-up contribution.

On the employer side, you can contribute up to 25% of your net self-employment income. This is calculated by taking your gross income and deducting half of your self-employment tax as well as the contribution you’ve made as an employee.

The total combined contribution as an employer and employee for 2023 cannot exceed $66,000 (or $73,500 with the catch-up contribution if you’re 50 or older). Keep in mind that these limits can change annually based on IRS guidelines.

John and Sarah took full advantage of this dual role, contributing the maximum possible amount, thus optimizing their tax benefits and accelerating their retirement savings.

Taking Minimum Qualified Distributions (MQDs) from a Solo 401(k)

Retirement savings plans are designed for the long haul, and premature withdrawals can lead to penalties. With a Solo 401(k), you generally can’t take distributions without penalty until you reach the age of 59½. Early withdrawals are subject to a 10% penalty in addition to income tax, unless you qualify for an exception such as disability or severe financial hardship.

However, the Solo 401(k) does have a unique provision: the loan feature. As we touched upon earlier, this allows you to borrow up to $50,000 or 50% of your account balance (whichever is less), providing some flexibility in case of financial needs.

Upon reaching the age of 72, you’re required to start taking minimum distributions, much like traditional IRAs and 401(k)s. If you’ve opted for a Roth Solo 401(k), however, you aren’t subject to these required minimum distributions.

Potential Pitfalls of a Solo 401(k)

While a Solo 401(k) is a powerful tool for self-employed individuals, it’s not without potential pitfalls. Let’s address some common misconceptions:

  1. Employee Eligibility: If you hire employees who meet eligibility criteria (generally those working more than 1,000 hours a year), you’ll need to include them in the plan, effectively turning it into a standard 401(k) with all its associated costs and complexities.
  2. Administrative Effort: Setting up and maintaining a Solo 401(k) does involve more paperwork than a SEP IRA or a SIMPLE IRA. You’ll need to file an annual report on Form 5500-EZ with the IRS once your plan assets exceed $250,000.
  3. Limited Creditor Protection in Some States: While Solo 401(k)s generally offer solid creditor protection at the federal level, some states may not extend the same level of protection against creditors’ claims.
  4. Possible Tax Implications: Remember, withdrawals from a traditional Solo 401(k) are taxed as ordinary income in retirement. Depending on your future tax situation, this could potentially result in a hefty tax bill.

John and Sarah, in their journey, were initially overwhelmed by the administrative requirements of the Solo 401(k). However, by setting up systematic processes and seeking guidance from financial advisors, they found the benefits far outweighed these challenges.

Comparing Solo 401(k) with Other Retirement Plans

Understanding the Solo 401(k) in isolation is beneficial, but it’s equally essential to compare it with other retirement plans to gauge its relative merits. Let’s compare it with two popular options for the self-employed: the SEP IRA and the SIMPLE IRA.

Contribution LimitsUp to $66,000 in 2023 ($73,500 if age 50 or older)Up to 25% of net self-employment income, max $66,000 in 2023Up to $15,500 in 2023
Catch-Up ContributionsYes, for age 50 and olderNoYes, for age 50 and older
Employer ContributionsYes, up to 25% of net self-employment incomeYes, up to 25% of net self-employment incomeYes, mandatory 2-3%
Loan ProvisionYesNoNo
Roth OptionYesNoNo
Required Minimum DistributionsYes, starting at age 72 (Not required for Roth)Yes, starting at age 72Yes, starting at age 72

Comparing these options, John and Sarah realized that the Solo 401(k) provided the most significant potential for retirement savings, given its high contribution limits and the availability of loan provisions and a Roth option.


Choosing the right retirement plan is a crucial financial decision. If you’re self-employed with no full-time employees, a Solo 401k can offer an excellent opportunity to save for retirement while reaping significant tax benefits.

In their journey, John and Sarah embraced the Solo 401(k) as a cornerstone of their retirement strategy. By making the most of its unique advantages, they now look forward to a future with financial security and peace of mind.
